These three stamps come from a sheet of six which also include
Spider Monkey (Atteles geoffroyi), Margay (Leopardus wiedii) and
Mountain Lion (Puma concolor). I had seen this sheet listed on the
Nicaragua Post
web site early in 2002 but could not find it being
advertised in any supplier's list. Consequently, I decided to buy a few sheets
directly from the postal authority.

Although the stamps show the date 2000, they were apparently not issued until
27 November 2001.
